That was my point, to each his own
your d series was faster than your k series, but you're prob way happier with the k than the d.
I personally am about hp/$ and a k doesn't make sense to me. I never cared about wow factor ( besides my header). I cared about whAt worked and made power for a reasonable amount of money.
People forget I owned the ANR header before anyone else, RMF sent me headers, I had John from hytech sent me a header for free , etc. I owned all the baller headers back in the day when most people had dc sports.
But along the way I became about business and opportunity. Sure quality of hytech is awesome, but rmfs mild steel header was better. Hytechs $1000 header was worse than a $600 header.
Then I was tapped by a company to test the new hytech rreplica header. And this $500 header was just as good as the $1000 custom unit John built from hytech
at that point I became about power, availability, price.
I'd rather own a $400 header that did the same thing as a $1000 header. Others feel differently
doesn't mean the quality of my build was bad or worse
